How to make coffee by hand? How to control the degree of grinding and water temperature?
After understanding the principle of hand-brewing coffee, we should understand that the focus of making a good cup of hand-brewed coffee lies in the extraction time, that is, the time when coffee powder reacts with hot water. In addition to time, there are other important elements to pay attention to. As long as you master these elements, you can greatly improve your chances of successfully brewing a good cup of coffee!

Uniformity of coffee powder particles
The extraction speed of fine coffee powder is fast, while that of coarse coffee powder is slow. We can adjust the size of coffee powder according to the flavor of coffee beans and their own blending habits. However, whether large or small, if the powder particles are not uniform, it is possible that when the fine coffee powder has begun to release bitter molecules, the coarse coffee powder has not been fully extracted and can not show the most original and unique flavor of coffee beans.
Coffee powder particle size
The finer the coffee powder, the longer the hot water will flow through the coffee powder.
Filter paper thickness
The thicker the filter paper is, the slower the flow rate of the extract is, and the longer the interaction time between hot water and coffee powder is.
Speed and mode of water injection
Water injection is uniform and stable, so that the extraction speed of coffee powder is the same. In addition, the height of water injection will also affect the water temperature, so it is recommended to get as close to the filter cup as possible and inject water by repeated loops.
Water temperature
The higher the water temperature, the faster the extraction. It is generally recommended that deep-roasted coffee beans should be boiled at 90C (80m / L) and lightly roasted beans (90m / 93C).
